BARREL CONSTRUCTION.

Specification of Letters Patent.

f Patented Nov'. 21, 1911..

. Application led January 31, l1910. Serial No. 541,044.

' barrel and which shall be durable and capable of withstanding rough usage.

In carrying out the' invention an outer shell of metal is provided, the -i-nsidel of which is lined with wooden staves and' heads of peculiar construction, which willv be described more fully hereinafter. j

In the drawingsv accompanying this specification, a preferred embodiment of the invention is shown.

The like parts in'the several views are given the same reference numerals.

Figure 1 is a sectional elevation of -a barrel embodying the invention. Fig. 2 is a sectional view onthe line 2*2 of Fig. l, looking in the direction of the arrows. Fi 3 is a small plan view of the barrel hea Fig. 4 is an enlarged detailed view of aA portion of the barrel, showing the method ofplacing the head in position. v

An outer vmetallic shell, preferably of galvanized iron, is shown at 1. This shell is preferably corrugated in order to provide greater rigidity and permits the use of lighter material. It has been found that sheet iron one-fourth of an inch thick will provide the necessary strength for an ordinary beer barrel. The ends of the metal shell 1 are' threaded and into these threaded portions a head, also bf sheet metal, is

screwed. `These heads are preferably hollowed out or Hanged in the mannershown and may be provided with a number of projections, such as 3, to provide for turning and screwing the same into position.

A number of woodenl Steves-4 are `placed j in position in the interior of the shell 1. These staves 4 are. wider inthe center and tapered toward the ends, similar to the ordiv nary barrel stave, in order to provide for the bulging central portion of the, barrel. Two 'ofdthe staves,l however,- such as 5, are formed' with one straight edge and one stave,

' thus such 'as 6, is formed with two parallel straight edges. The object of this construction is to permit all of the staveswith the` exception of stave Globe placed in position and then the stave 6, which is of such a width as to permit it being driven into place, is inserted and locks all of the-staves in place.

The staves are preferably formed with tongues on each end which, when the same are in position'l in the interior of the shell l,

enter an annular groove in the wooden head 7, when the same is placed in position thereupon.

The metal heads 2 are then screwed into, position against the wooden headsA 7, locking thel whole together.. The method of placing the Wooden head 7 and: the metal head 2 in position is clearly shown in 4 and a complete barrel with all'fthe parts assembled is shown in Fig.. 1. A bunghole may be provided in one of the staves and an opening, preferably somewhat larger than the bung-hole, provided in the metal shell 1. The adjoining edges of the several staves are also preferably constructed with a tongue and groove which interlit .and these joints, as wellv as the joints between the ends of the staves and the wooden heads, may be coated with pitch before the same are assembled, which insures an absolutely tight construction and prevents any leakage. f

As the wooden portions of the barrel are protected against injury in use and handling, it has been found that a thickness of three-eighths of an inch is suilicient for the ordinary beer. barrel.

An ordinarybeer barrel constructed entirely of wood weighs approximately eighty pounds, while a barrel constructed as herein described will be from eighteen to ytwenty pounds lighter and will be more durable and of a longer life.

As the metal shell protects .the wooden portions of the barrel `from injury., and also does away with the hoops, a considerable saving inthe expense of repairs is effected and the cost of construction is at least no greater and probably less than the ordinary I construction.

It is not .to be understood rthat theinvention.. is limited to the exact `details of construction herein shownand described as it will beV obvious that the same admits of many changes, which may be desirable or necessar}7 in the different forms of barrels or easlts for various uses 'hat I claim l. )t barrel comprising in its construction a plural' y ot wooden staves each having a tongue on either end thereof, a metal shell within which said staves are positioned, wooden heads each provided with an annular groove arranged to receive the tongued ends of said staves. and nietal heads aranged to hold said wooden heads in position.

Q. A. barrel comprising in its construction a plurality ot' wooden staves tapering in width toward each end, two staves having one straight edge and one` curved edge, one slaveI having parallel straight edges, a metal shell Within which said staves are positioned, wooden heads, and metal heads arraagedto hold said wooden heads in position.l

3. A barrel comprising in its construction a plurality ot wooden staves each provided with a tongue at each end and also with a tongue and groove on opposite sides thereo'l, wooden heads each provided with an annular groove adapted to receive the tongues on the ends of said staves, a metal shell Within which said staves are positioned, and 30 metal heads screw-threaded in the ends of said shell and adapted to hold said Wooden heads in position.

4.-. A barrel comprising in its construction a plurality ot' wooden staves each provided 35 witha tongue at each end and also with a tongue and groove on opposite sides thereof, wooden heads each provided with an annular groove adapted to receive the tongues on the ends` of said staves, a metal shell within 40 which said staves are positioned, and metal heads screwed into the ends of s aid shell, said metal heads having dropped central portions and depending annular flanges adapted to bear against said Wooden heads 45 to force the staves into said annular groove.
